Symbols on your device

Rear of the device (nameplate)
Uninterrupted double or reinforced insulation as per Category II EN 61140.
Protection against electric shock.
The device is certified by TÜV Rheinland and carries the "Geprüfte Sicherheit"
(tested safety) seal of quality according to German law.
Device suitable for use on live parts.
Highest safety level. Applies to test and measurement circuits that are
CAT IV
connected to the source of the low voltage power system.
The device complies with European specifications.
Do not dispose of the device or accessories with general waste (see section on
„Disposal" on page 13).
LED display
An audible signal is issued when flow is detected, in case of dangerous voltage
(> 50 V AC / > 120 V DC) and if voltage is detected during the single-pole phase
test.
The ELV LED lights up in case of dangerous voltage (> 50 V AC / > 120 V DC)
and if voltage is detected during the single-pole phase test.
Even when the batteries are empty, the device indicates dangerous voltage by
lighting up the ELV LED.
Illuminated when flow detected (up to approx. 500 kΩ) (see section on „Flow/
diodes test" on page 12).
LED R is illuminated in case of right rotation. LED L is illuminated in case of left
rotation (see section on „Rotation field test" on page 12).
Indicates the voltage polarity as follows:
12
+
AC: LED + and -12 V light up
+ DC: LED +12 V light up
- DC: LED -12 V lights up and "-" appears on the LC display
(see section on „Voltage test" on page 12)
Shows the measured voltage. In case of a 230 V socket, for example, the LEDs
50
24
are illuminated up to 230. The following voltages can be displayed by the LEDs:
12, 24, 50, 120, 230, 400, 690, 1,000 V.
LC display
Symbol lights up when the battery is low.
Shows the measured value.
